18 m 5-axle low-bed semi-trailer

Product advantage

1. Powerful Load Capacity for Heavy-duty Scenarios

• With a rated total mass of 70000 kg and paired with LUCKSUN 16T axles, it easily handles the heavy transportation of bulk cargo such as sand, gravel, and building materials, making it an ideal choice for engineering logistics and commodity transportation.
• The chassis uses 3.0mm thick checkered plate, offering enhanced structural rigidity and deformation resistance to withstand long-term heavy loads without damage.

2. Reliable Safety Configuration for Stable Driving

• Equipped with WABCO brake valve group, it features fast braking response and even brake force distribution, significantly improving driving safety in complex road conditions.
• The 10-tablet 13mm×90mm leaf spring shock absorption system provides excellent shock absorption, effectively reducing the impact of bumpy roads on the vehicle and cargo to ensure transport stability.

3. Practical Structural Design for Multi-scenario Adaptation

• The 800+400 fence structure allows flexible height adjustment, meeting the anti-spill needs of high fence plates and enabling quick disassembly to load extra-long cargo, adapting to the transportation of bulk, oversized, and other types of goods.
• The 4-axle layout evenly distributes the load, and with 12R22.5-18PR heavy-duty tires, it has lower ground pressure, ensuring stable travel on unpaved roads such as construction sites and rural areas.

4. Outstanding Durability with Low Maintenance Costs

• The combination of high-strength steel plate chassis and heavy-duty axles offers strong wear and corrosion resistance, adapting to long-term and high-frequency transportation operations and reducing maintenance frequency.
• Standardized configurations (such as WABCO braking system and LUCKSUN axles) feature high part universality, enabling quick repair and replacement and lowering the total life cycle cost.

Structural Design and Chassis Strength

High-Strength Frame Construction

The chassis of this 18 m low-bed semi-trailer is engineered using high-tensile structural steel, ensuring excellent resistance to bending, torsion, and fatigue. The long deck length allows transport of large machinery while maintaining a low center of gravity.

Unlike low-quality trailers that rely on thinner steel or inconsistent welding, this model emphasizes structural integrity over weight shortcuts, significantly extending service life.

3.0 mm Pattern Base Plate

The 3.0 mm patterned base plate provides:

• Enhanced anti-slip performance during loading

• Increased resistance to deformation under point loads

• Better durability when transporting tracked machinery

Low-quality trailers often use thinner plates (2.0–2.5 mm), which deform quickly and require frequent repair.

Axle and Suspension System

LUCKSUN 16T Heavy-Duty Axles

The trailer is equipped with LUCKSUN 16-ton axles, known for stable performance under heavy loads and long maintenance intervals. With five axles distributing the load evenly, the trailer ensures:

• Reduced axle stress

• Improved road compliance

• Enhanced braking efficiency

Inferior trailers often use unknown axle brands with inconsistent heat treatment, leading to premature bearing and spindle failures.

Reinforced Leaf Spring Suspension

The 10-layer leaf spring configuration (13 mm × 90 mm) offers excellent shock absorption and load distribution. This design protects both the cargo and trailer structure during transport on uneven roads.

Low-end alternatives typically reduce spring layers to save cost, resulting in:

• Excessive vibration

• Cracked frames

• Higher tire wear

Braking System and Safety Performance

WABCO Brake Valve Group

The braking system uses WABCO components, ensuring precise air pressure control and fast response times. This is a critical safety factor when transporting 100-ton loads over long distances or downhill routes.

Compared with non-branded brake systems commonly found on low-cost trailers, WABCO delivers:

• Shorter braking distance

• Stable braking under full load

• Reduced risk of air leakage or valve failure

For fleet operators, braking reliability directly impacts insurance costs, accident risk, and regulatory compliance.

Tire Configuration and Load Stability

12R22.5 18PR Tires (20 pcs)

The trailer is fitted with 20 heavy-duty 18-ply tires, designed for high load capacity and long-distance hauling. This configuration ensures:

• Even load distribution

• Reduced blowout risk

• Lower heat buildup during continuous operation

Low-quality trailers often cut costs by using lower-ply tires, which dramatically increases the risk of roadside failures and downtime.

Application Scenarios

This 18 m 5-axle low-bed semi-trailer is widely used for transporting:

• Construction machinery (excavators, cranes, loaders)

• Power generation equipment (transformers, turbines)

• Mining machinery

• Steel structures and prefabricated modules

• Large industrial equipment

Its versatility makes it suitable for domestic transport and cross-border logistics projects.
